I had stopped using 2010 since my organization has not rolled out this version yet. I’ve been working with my file in 2007 until today. I opened the file in 2007 and the application crashed as soon as I tried to access a column filter. I reopened the file in 2010 and was able to save the file and reopen it with no further problems. I will continue to work on the file in whatever version works without crashing. For now that is 2010. I’m saving the file in 2007 file format.
